Implausible most of the time; on the other hand, most mystery crime series are, and we usually just suspend disbelief for awhile. For most of this series the stretch of reality was not too bad; but the resolution at the end was pretty hard to swallow (had a certain logic to it, but .... I won't spoil it). But I was curious how it would resolve, so give it a slightly above average rating (too often with other series I just lose interest and cease to care). Perhaps a 3 or 4 episode series, rather than 6 episodes, would have been better.
